The research question being discussed is on primate evolution. From the scholarly article concerning Phylogency of living primates. The primary argument is the evolution is both complex and controversial. This is because the phylogeny is robust, and it shows primate evolution from the past to recent times (Seuánez HN 2011). It clarifies various controversies concerning taxonomy and provides recent data and findings on human evolution. The ancient lineages, different rates of evolution and dispersed distributions of insertions in the primate lineages are discovered (Perelman 2011). This helps in explaining the human selection and adaptation, the discovery of zoonotic diseases, comparative mammalian genomics, and the taxonomy of primates and protection of endangered species.
On the other hand, from the popular press on the color vision article the primary argument is that it tends to discover how our eyes reflect primate evolution. This is explained by the fact that we view the world as an array of hues (Crone and Robert 1999). It can be noted that the mixture of a certain beam of light can produce color. This is what explains the characteric of human vision known as trichromacy (Gegenfurtner 1999). This comes up in the retina which is a part of the eye where light passes through and hence information is transmitted to the brain. Trichromacy is present in primates, but absent in some animals in the animal kingdom. The primate trichromacy can thus be used to show primate evolution in terms of color vision (Hurvich and Leo).
The evidence that the authors use is that the visual pigments that primates have depicts that color vision evolved in an interesting manner and that the brain is adaptable to this. This is based on empirical research and common knowledge. The evidence is convincing since it explains the reason why people may at times see different colors on a computer monitor is because of trichromacy. The authors state that further research should be carried out to show why individuals cannot be able to see in infrared light. The references are a good number; they are a combination of both the past, and the present and this further strengthens the research. The article was published in April 2009, and it is intended for public interest. The writing style is appropriate since the language used can be easily understood. The strengths of the article are that it explains a very important part of the body the eye and its significance in color vision. The article was logically organized since its contents flowed easily, and the materials used were relevant.
